If you've toured Destiny of Velious, you know of the unused Wizard Spire in the Eastern Wastes and abandoned Dragon Ring in the Great Divide. An upcoming live event, recently pushed to Test and Test Copy by Gninja, seeks to rebuild them. These events will be more like Public Quests than past events.
Both events share one currency [tokens] and currency can be obtained in two ways. There are blue collectibles that spawn around the event area. The number of collectibles vary based on the progress of the event. The second way is by defending the respective areas from the attacks that happen when the events kick off. When you enter the area you should receive a quest.
When the events kick off the area should be attacked by waves of attackers. Defeating these attackers and minimizing NPC casualties will reward progression. Allowing them to die will slow progression. As the events gets further in progression the difficulty of the waves will increase.
There is no planned tradeskill component to these events, without engaging in combat, there are options to acquire tokens. Gninja again:
The tokens also spawn around each of the areas as ground spawns like in Tinkerfest.
This event may go live with, or after Game Update 60, it's not clear.
